Bob posted up a follow up to the previous PCB post – his photo resist PCB process – “Don’t be scared away with this method. It’s easy! The only thing I do different is I use regular ordinary fluorescent lights ($8.00 at WalMart for a small fixture with bulb). Exposure times go from 90 seconds to 10 minutes but it works just the same. I don’t have much in the way of descriptions but I have pictures of every step I use here” – Link.
